Are Elevators Next?

Well, it happened tonight. A rap song, "It's Hard Out Here for a Pimp" from "Hustle & Flow" won the prize for best song at the Academy Awards. I remember the first time I heard a Beatle song in an elevator -- impossible! No, not impossible simple the place popular songs go to die. Hip Hop and Rap have been popular for quite a while but not enough to break into the staid format of the Academy Awards. And now not only a rap song but one that needed to be toned down to even be performed at the Oscars. I wonder how long it will be before we hear rap in the elevator? And what will take its place in the controversial slot of popular music?
